IMHO there are 2 key changes that would make this game better. I know they have been suggested before, but just want to keep them out there for consideration.
1. Change the barbarian icons to show the barbarian level. Too much time is wasted looking for a suitable one to loot.
2. Free one-click resource collection. It takes way too long to do this when you have a few cities, so I am not willing to add to the burden by making more cities. An alternative would be to make feathers more affordable, maybe 1-2 turquoise each time.
